I almost ruined my entire sound system with one mistake

Putting together a sound system is a daunting task. You need to pick out speakers, a receiver, and a subwoofer. A lot of people focus on the speakers, rightly so, but the subwoofer is a very underrated part of the setup. I foolishly looked at it as something to add at the very end, but if I had to do it again, I’d spend a lot more time (and money) on my subwoofer.
